I’m running Windows Server 2008/R2 with SharePoint 2010 Enterprise. I have installed the ArcGIS Geolist Web Part and ArcGIS Map Web Part on the main portal. Going to a site and selecting edit page I see the “Add a Web Part” links in the zones on the page. I click on the link and selecting either ArcGIS web part places it in the page. After doing this the page editing controls become inactive (grayed out). The Edit button loses its icon altogether. Clicking on the “Add a Web Part” in any zone results in absolutely nothing happening. After adding the first web part, at the bottom left of IE I get a warning “Done, but with errors on page.” I just go up to the pull down arrow of the ArcGIS web part and select Delete. Once the web part is deleted the pages editing controls on the ribbon become active again. I can add other web parts, as many as I want without any problem. This only occurs when I add in either ArcGIS web part. Any help to resolve this problem would be appreciated.
